Acid Rain & Environment To know how acid rain affects the environment

Acid Rain The diagram shows a coal fired power station (producing waste gases into the atmosphere). A cloud is seen moving across to Sweden, where acid rain falls onto the forest… Rearrange the sequence of letters showing how the acid rain is formed…

Acid Rain Rearrange the sequence of letters showing how the acid rain is formed… A – acid rain pours from the clouds B – this releases sulphur dioxide into the atmosphere C – burning of fossil fuels, e.g. coal D – sulphur dioxide dissolve in the moisture of the cloud E – the cloud blows to another country CBDEA

Acid Rain Your task is to investigate what products are released when acid rain falls on the rock marble How could you prove that the gas released was CO 2 which increases global warming? Limewater is our test gas CO 2 – all we need to do is collect some of the gaseous product and bubble it through limewater (if the limewater goes cloudy then the gas is CO 2 )

Risks Complete a risk assessment, highlighting the possible risks involved with this experiment; and action to take to minimise the risk… For example: - Acid is an irritant – wear eye protection and do not touch The reaction is exothermic (gives out heat) so be careful of hot apparatus Normal laboratory rules must be followed, especially as there is glassware which is easily damaged

Risks

Experiment Add a small amount of sulphuric acid to a small amount of marble chip Bubble the gas through limewater, and note any changes in appearance Acid rain reacts with a variety of rocks – as CO 2 is released this greenhouse gas can greatly influence global warming rates…

Acid Rain & Soil A layer of soil covers much of the Earth’s surface (made of weathered rock particles; humus (decaying animals and plants); water; air; and living creatures) Soil supplies plants with water and important nutrients (as well as helping anchor the plant to the ground) However, soil pH is very important, as different plants grow in different soils based on their pH – acid rain can greatly affect the soil, so changing which plants can live there
